Interesting Web find:
"A hostile state doesn't actually need to persuade Britain that Russia is wonderful. That's Cold War thinking. A much cheaper objective is to make Britons distrust one another, distrust expertise, distrust elections, distrust journalism and distrust institutions; amplify whichever existing grievances are most useful; make politics permanently furious; and leave everyone convinced that the person living three streets away is the enemy.
At that point, a missile defence system is somewhat beside the point.
And that's where education becomes national infrastructure. Not teaching children what political conclusions to reach, quite the opposite...teaching them how to ask: Who is making this claim? What's the original source? What evidence would disprove it? Is this photograph actually from the event being discussed? Does this graph start at zero? Is that account a person? Why is this story making me angry? Who benefits if I share it before checking it?
Those aren't left-wing skills or right-wing skills... they're democratic immune-system skills. The more seriously you regard hostile information operations as a national-security threat, the harder it becomes to regard teachers, librarians, universities, public-service journalism and media literacy as fluffy civilian expenditure that can be trimmed whenever somebody wants another weapons programme.
A fighter aircraft protects British airspace for perhaps thirty years.
A teacher who teaches thirty children a year how to recognise bullshit may remain operational considerably longer."
